Go straight ahead!!

massugu ni susunde

How to say in Japanese: Straight Ahead

You are lost and you are asking for direction. 

The man tells you　真っすぐにいってください massugu ni itte kudasai.

Then you should just go straight.

Usually it follows by に ni, which indicates direction.

But if you want to say, look straight ahead, you add 前 mae.

It become 真っすぐ前を見る massugu mae wo miru.

Notice the を wo is used. That`s because 真っすぐ前 massugu mae becomes a noun.

If you are confused with all the particles, just drop it. 

真っすぐいって massugu itte

真っすぐ前見る massugu mae miru

People will understand you too, and dont worry, it wont sound weird either. 

It is normal even among Japanese to drop particles.
